How Is Potassium Oxalate Synthesized?

Potassium oxalate can be synthesized by reacting oxalic acid (H2C2O4) with potassium hydroxide (KOH). The reaction equation is:

H2C2O4 + 2KOH → K2C2O4 + 2H2O

The oxalic acid and potassium hydroxide are mixed together in water, and then heated until the reaction is complete. The resulting solution is then allowed to cool and the potassium oxalate crystals will form.

It is important to handle oxalic acid with care, as it is toxic and can cause skin and eye irritation. In addition, proper ventilation should be used when heating the reaction mixture to avoid inhaling any harmful fumes.
